Vista - how to discover is aero is running

hi dear group,

how to detect if aero is running instead of basic standard GUI?

thanks

Roberto,
Current running theme can be queried via the registry key of
"HKEY_CURRENT_USER\Software\Microsoft\Plus!\Themes\Current".
Other theme related information can be found under
"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ThemeManager"

Hope this helps!

Eddie,

thank you,

btw. but the aero theme will be the unique within the 3D powered UI?
aren't user personalization changing the name of these keys (eg. a user
can save as "mytheme" a changed UI)?

Also, if there isn't some kind of theme API built into Windows for this, is
the registry key in question is going to be stable for the next 3-4 years?
It seems like the result of this route would be a managed app that has a
single point that is VERY coupled into the internal workings of Windows
(i.e. the registry), as opposed to being linked at a more abstract (and
compile-checked) API

Hi,
the C# interop for this API is

[DllImport("dwmapi.dll")]
private extern static int DwmIsCompositionEnabled(ref int enabled);

I personally, check for Aero this way:

public static bool Applicable
{
get
{
try
{
if (System.Environment.OSVersion.Version.Major < 6) return
false;
int enabled = 0; DwmIsCompositionEnabled(ref enabled);
if (enabled == 0) return false;
}
catch { return false; }
return true;
}
}

Hope this helps,
Jan
